Recently, I have been conducting swing trades in the Bitcoin spot market with the $BTC/USDT trading pair, utilizing the support and resistance mechanism of the Bollinger Bands' upper and lower bands: when the price drops to the lower band and the RSI is below 30, I set up long positions at this point and place the stop loss 0.5% outside the lower band; if the price retraces to the middle band, I take profits in batches. This method combines oscillation ranges and momentum indicators, making each entry and exit more disciplined, while the average profit per trade is approximately 3%, with a risk-reward ratio better than that of general market orders.
